Piglets have poor thermoregulation function after birth, and it is easy to freeze to death due to poor heat preservation. Poor environmental conditions or improper foster care, sows bite their young, resulting in the death of piglets. Piglets lack innate immunity after birth and cannot produce antibodies themselves. 10 began to produce antibodies after the age of 0, and it was protective, so it was easy to get sick. Common diseases include pneumonia, diarrhea, hypoglycemia and congenital tremor. Under some stress conditions, such as poor sanitation and rude attitude of staff, there will be vicious habits such as biting tail or ear, which will lead to infection and even death; After weaning, the changes of environment and feed will cause stress of piglets and affect their survival rate and growth.
Therefore, it is necessary to provide good maintenance conditions and use a dry fermentation bed to keep the pigsty dry and warm. The temperature of the pigsty should be kept at 22-30℃, not lower than 20℃ in winter, and the relative humidity is 50%-80%. At the same time, the pigsty should be ventilated frequently to discharge harmful gases. Try to create conservation conditions suitable for the growth and development of piglets. This feeding method is to spread sawdust with a thickness of 50 cm in the pen house, and the strains of the fermentation bed are evenly scattered into the sawdust to make the surface of the fermentation bed soft and warm. In the fermentation process, the temperature of the center layer of sawdust can reach 50-60 degrees, and the temperature transferred to the bed surface is 25-30 degrees. Is a perfect constant temperature bed, constant temperature all year round, saving energy costs such as coal and electricity, convenient to keep warm. The surface temperature of dry fermented mattress material is easy to keep warm.
